SPECIFICATION forming part of Letters Patent No. 527,347, dated October 9, 1894.

Application filed June 11, 1394- Serial No. 514,243- (No model.)

To all whom it'may concern.-

Beit known that I, WILLIAM S. ROBINSON,

a citizen of the United States, residing at Fancy Farm, in the countyof Graves and State of Kentucky, have invented new and useful Improvements in Mechanism for Opening Windows, Transoms, (he, of which the follow is a specification.

My invention relates to mechanism for opxo crating window sashes, transoms or similar structures, of that class which are hung or journaled to swing or revolve in the window frame, and it has for its objects to provide a mechanism actuated to open and close the r 5 windowsash by a single operating device; to provide a mechanism for which the bolt fastening the sash in its closed position is released and the sash swung to the desired open position bya single, continuous action of the operating device; to provide amechanism wherein the sash is released fromits locked,

closed position, swung to the desired open position and automatically held in such open position; to provide a mechanism wherein the sash is swung to and held in open position and released from the adjusted open position to swing automatically to its closed position, by a single operating device; and finally said invention has for its object to improve generally the construction and operation of Window sash operating mechanism.

To these ends said invention consists in the novel construction of parts; in the novel combination of parts and in the novel arrange- 3 5 ment and operation of parts hereinafter described and claimed, reference being had to to the accompanying drawings, wherein- Figure 1 is a side elevation, the sash being in aslightlyopen position. Fig. 2isafrontview,

the operating mechanism being arranged to operate two adjoining windows. Fig. 3 is a detail side view, the mechanism being in its normal position or thatposition it takes when the sash is. closed. Fig. 4 is a perspec- 4 5 tive view, the parts being detached and in their relative position when the window has been released from its adjusted open position and is about to automatically swing to its closed position. Fig. 5 is a detail perspective view of the crank lever hereinafter described. i

In said drawings the reference-numeral 1, designates a window-frame and2 a sash journaled to swing or revolve therein on studs 3. A bracket or other suitable support 4, constructed preferably in two sections 4 and 4 connected together by a pin 5, is designed to be secured to the face of the window frame 1, at the side of the window sash and in or about the same horizontal line with the piv- 6o otal support 3 of said sash, and journaled to turn in said bracket is an axle 6, having elongated spindles 6. Said axle carries a rigidly fixed arm 7, adapted to be moved in a vertical plane'to rock or rotate the axle in its bearings. I

The numeral 8, represents a crank-lever adapted to be fitted upon the axle 6,at varying positions of adjustment, dependent upon the distance from the inneredge of the window-frame at which the bracket 4, is located. Secured to the side of the window sash adjacent to the bracket and at a point above the pivoting studs 3, is a plate 9. Connected pivotally at its opposite ends to said cranklever 8 and said plate 9 is a link 10, whereby an operative connection is established between the window sash and the sash-swinging arm 7. It is found that in different windows the sashes are arranged at various dis- 8o tances from the faceof the window frame, and to accommodate the mechanism to such variously arranged sashes I provide a means of adjusting the operative length of the link 10, which consists of two seriesof perforations 11 formed in said link and the connecting arm of the crank-lever 8,said perforations being adapted to be brought into register and the link and lever connected at the desired adjustment by means of a pinor other device.

The numeral 12, indicates a sliding bolt secured to the window sash and adapted to engage a bolt socket in the sill to lock the sash in its closed position. Running from the up- I per end of this bolt and over a pulley or 5 movable anti-friction device 13 at the top of the sash is a flexible connecting medium which at its other end is secured to a ring or oted a swinging trip-dog 18, the active end of which lies behind the pawl 17, and at a proanalogous element 14, said ring being located slightly above the outer end ofthe arm 7, when said arm is in its elevated or normal position. An operating device 15, is secured at one end to said ring and passes through an eye formed in the outer end of the arm 7, its other end extending to any suitable point within reach of the operator. The provision and arrangement of the ring or other connecting element 14, is made so that a pull upon the operating device 15 will release the bolt prior to coming into operative engagement with the arm 7. V.

The operation of the mechanism as thus far described will be obvious to those skilled in the art, but maybe brieflystated as follows: The window sash being in its closed and locked position a pull upon the device 15, will release the bolt, unlocking the sash and leaving it free to be opened. A continuance of the pull brings the ring 14 into contact with the outer end of the arm 7 which is carried: downward with the ring, whereby the axle 6' is rocked or rotated and through the 1nstru-- mentality of the crank-lever 8 and link 10, the sash is swung from its closed position to an open position, as will be understood and as shown in Fig. 1.

It is desirable that the sash may be opened to greater or less extent'for ventilation, ac-

cording to the condition of the weather and; that when opened it shall be held in itspo For this purpose 1 form ratchet teeth 16, of desired number and distance apart in the hub or butt-end of the; arm 7, and upon the bracket 4, I provide a; pivotedpawl 17 which automatically drops into engagement with one or another of the teeth 16, according to the degree to which the 1 window sash is to be opened, and thus se-I sition of adjustment.

curely holds the sash in that position.

In order to release'the pawl 17 from the teeth, to permit the window sash to assumef its closed position, I employ the following instrumentalities: Upon the bracket 4 is pivdetermined distance in rear thereof upon the 7 7 hub of the arm 7, is arranged a fixed finger 19, whereby upon the operator drawing downward upon the device 15, the said finger 19, strikes against the trip-dog 18 which in its forward movement lifts the pawl 17 from engagement with the teeth 16, and holds it out of engagement until the arm is elevated when it is thrown into operative position as hereinafter described. The arm 7 is thus released and the sash will automatically, by its own gravity, swing to its closed position. In cases where the pivotal engagement of the sash will not permit it to swing closed by gravity any suitable device can be employed,

such as a spring, to draw the arm to its normal, elevated position and close the sash when the pawl is released from the teeth.

In order to prevent the arm 7, descending too far and thus allowing the trip-dog to swing out past-the pawl 17, aspring or elastic stop-plate 20 is secured to the bracket 1,

and at its outer end engages a seat 21, in the arm 7, when the said lever has been lowered the proper distance to release the pawl 17. This stop-plate also serves as a guard to prevent the lever being drawn down far enough to release the pawl when it is desired to open the window, as its outer end will meet said arm at the proper time in its descent and offer sufficient resistance to notify the operator that the window-sash has been brought to its wide open position.

When the arm has been released and is carried to its elevated position by the window in closing (or by a device such asa spring in windows differently hung) the inclined nose of the pawl 17 will strike against the arm 7 and swing the trip-dog back, when the parts will be in correct relative position for operation.

I have described my invention as applied for use in operating a single window, transom or similar structure, but it is obvious that it is adapted to be used to operate two adjoining structures, as shown in Fig. 2, the only change necessary being the provision of an additional locking bolt, a flexible c'onnec- 5 tion thereof with the ring 14, and a second bell-crank-lever and link.

Having thus described my invention, what I claim is- 1. In mechanism for operating swinging windows, transoms and like structures, the

combination with a sash-locking device, of an axle, means connecting said axle with a window-sash, a swinging armcarried by said axle and a device operatively connected to said sash-locking device and to said swinging arm, forunlocking the sash and swinging the 1 same to anopen position,substantially as described.

2. In mechanism for operating swinging windows, transoms and like structures, the combination with a sash and a locking'device therefor, of an axle, a crank lever secured to said axle, a link pivotally connected to said sash and said crank lever, .a swinging arm carried by said axle, and a device operatively connected to said sash-locking device and to said swinging arm, for'unlocking the sash and swinging the same to an open position, substantially as described.

3. In mechanism for operating swinging windows, transoms and the like, the combination with an axle, means connecting said axle with a sash, a sash-swingin g arm carried by said axle, means "for holding said arm in various positions, and a finger carried by and automatically releasing said arm, substantially as described.
